We investigated the changes in the hepatic proteome in murine models for toxic-induced fibrogenesis and sclerosing cholangitis. A comprehensive comparison of protein changes observed is made and the mechanistical basis of the expression changes is discussed. Hepatic fibrosis was induced by repetitive intraperitoneal CCl4 treatment of BALB/c mice or developed spontaneously in BALB/c-ATP-binding cassette, subfamily B, member 4 (Abcb4) knock out mice. Fibrosis was verified by a morphometric score and assessment of hydroxyproline content of liver tissue, respectively. The innovative difference in-gel electrophoresis (DIGE) technique was used to analyse protein expression levels of the mouse proteome. Results were confirmed by Western blotting and real-time RT-PCR. In CCl4-induced fibrosis 20 out of 40 and in BALB/c-Abcb4(-/-) mice 8 out of 28 differentially expressed proteins were identified utilizing DIGE. Only two proteins, selenium-binding protein (Sbp2) and carbonic anhydrase 3, have been unidirectionally expressed (i.e. down-regulated) in both models. Relevant differences in the pathogenesis of toxically induced liver fibrosis and sclerosing cholangitis exist. The only novel protein with regard to liver fibrosis depicting a unidirectional expression pattern in both animal models was Sbp2. An explicit protein function could not be clarified yet.

In the present work, the effect of dioscin against liver fibrosis in rats caused by carbon tetrachloride (CCl4) was confirmed. Then, the differentially expressed proteins from rat liver were identified using two-dimensional differential in-gel electrophoresis technology. Ten new biomarkers including protein disulfide isomerase A3, selenium-binding protein 1, glutamine synthetase, senescence marker protein 30, hemopexin, keratin 8, keratin 18, vimentin, Annexin A5 and dermatopontin associated with liver fibrosis were found and validated, and new insights through affecting multiple drug targets and biological processes were also provided to reveal the mechanisms of dioscin against hepatic fibrosis for the first time.
